Party Hosting Ideas?

Have an horsdevours party. Make it (I know you don't want a theme) horsdevours from a certain country, and everyone bring a NEW horsdevours that they have never done. You can create great invites by copying and pasteing pictures, quotes, etc. off the internet. You could get into this with clothing too. Have everyone bring a bottle of something or a drink from a certain country kindof like a wine tasteing. Something they haven't tried, and you supply the food.
